Increasing the temperature at the earth's surface, known as global warming occurs because the amount of gases CO2 and methane (CH4) increased in number in the normal condition. This also includes NO and CFCs (chlorofluorocarbons), which can cause a thousand times the global warming effects. Gases that cause global warming known as greenhouse gases, and the effect is called the greenhouse effect, this term was first proposed by Joseph Fourier in 1824.
